“…The inclusion of flavor was reported to increase feed intake for sows’ consumed diet [ 8 , 9 ]; however, there was no difference in feed intake among groups in the current study. Sweeteners, such as sucrose, lactose, glucose and saccharin, are added to feed to improve the feed intake of weaned piglets or lactating sows [ 5 , 26 , 27 , 28 ].…”

“…Flavor is widely used in diets for piglets and weaners [ 4 , 5 ] to improve feed intake and to ameliorate reduced feed intake post-weaning. The inclusion of flavor in sows’ diets has been shown to increase maternal feed intake and benefit the growth of their offspring [ 6 , 7 , 8 , 9 ]. Fiber content differs substantially across cereals, such as corn, wheat and barley, and they contain up to 9.0%, 11.3% and 18.6% non-starch polysaccharides (NSPs), respectively [ 10 ].…”

This study was aimed to explore how a high-quality diet or a flavor plus multi-enzyme diet affects the feed intake, nutrient digestibility and antioxidation capacity of lactating sows and the growth of their progeny. Thirty primiparous sows were randomly assigned to three treatments from d 2 of lactation until weaning (d 21): control (CON), with a basal diet; high quality (HQ), with 200 kcal/kg higher net energy than CON; or the CON diet supplemented with 500 mg/kg flavor and 100 mg/kg multi-enzymes (F + E). Sows fed with the HQ or F + E diets improved piglets’ live weight (p < 0.05) and average daily weight gain (p < 0.10), litter weight gain (p < 0.10) and piglet growth to milk yield ratio (p < 0.10). Compared with CON, the HQ and F + E groups increased the digestibility of ether extract, ash, neutral detergent fiber, crude fiber and phosphorus (p < 0.10), and the HQ group also increased dry matter, gross energy, crude protein, acid detergent fiber and energy intake (p < 0.05). Compared with CON, the F + E group decreased serum urea nitrogen and aspartate aminotransferase (p < 0.05) and enhanced superoxide dismutase, catalase and glutathione peroxidase, but it decreased malondialdehyde in milk supernatant (p < 0.05).

“…More piglets tend to be crushed during the hot season (Weber et al, 2009). Moreover, when surrounding temperatures are above the sow`s upper critical temperatures, her appetite is reduced, with a negative consequence for milk production (Quiniou and Noblet, 1999;Cabezón et al, 2017), which is in turn negative for piglet performance (Silva et al, 2018).…”

Straw vs. peat as nest-building material – The impact on farrowing duration and piglet mortality in loose-housed sows

Provision of nest-building material pre-partum is required by farm animal legislation in Norway, but as some farmers have problems with straw in the slurry system, alternative and finer-grained substrates could be of interest. The aim of the present study was to examine the effects of providing different nestbuilding materials before farrowing (peat and long-stemmed straw) on farrowing duration and piglet mortality. Sows of Norsvin Landrace x Swedish Yorkshire were loose-housed in individual farrowing pens with their litter throughout the entire lactation period, and provided with peat (n=18), longstemmed straw (n=17), or controls (n=18), from two days before expected farrowing until farrowing.Parity ranged from 1 to 9 (mean ± SE: 2.9 ± 2.0), of which 16 were gilts. The farrowing was video recorded, and the farrowing duration registered from first to last piglet born. Dead piglets were subjected to a post mortem.Sows provided with long-stemmed straw pre-partum had shorter farrowing duration compared to sows provided with peat or controls (P < 0.001). The percentage of stillborn piglets was also lowest among sows in the straw group compared to the other two groups (P < 0.001). Sows of parity ≥4 had longer farrowing duration than gilts and sows of parity 2-3 (P < 0.001). Farrowing duration (P < 0.001) and the percentage of stillborn piglets increased (P < 0.001) with an increasing number of total born piglets.Moreover, increased litter size resulted in a higher pre-weaning mortality (P = 0.016).The present study shows that provision of nest-building material before farrowing is important for the birth process of the sow as it reduces farrowing duration and percentage of stillborn piglets compared to controls without relevant substrate. Although peat gave better results than the control treatment, our results suggest that long-stemmed straw is a more appropriate nest-building material.

“…Feed intake was significantly higher in the intervention as compared to the control for at least one added flavor in various studies in pre-weaning piglets [ 47 – 50 ], post-weaning piglets [ 47 , 49 , 51 ], lactating sows [ 52 ], and pre-weaning calves [ 53 ], and there was a trend towards higher feed intake in pre-weaning and post-weaning piglets [ 47 ], as well as post-weaning calves [ 54 ]. Body weight gain was significantly higher in the intervention as compared to the control for at least one added flavor in several reports in pre-weaning piglets [ 52 ], post-weaning piglets, and growing pigs [ 47 – 50 , 55 , 56 ], as well as in pre-weaning calves [ 53 , 54 ] and in calves generally [ 57 ]. There was a trend towards higher body weight gain in post-weaning piglets [ 51 ] and post-weaning calves [ 54 ].…”

“…There was a trend towards higher body weight gain in post-weaning piglets [ 51 ] and post-weaning calves [ 54 ]. Furthermore, final body weight was significantly higher in the intervention as compared to the control group in pre-weaning piglets [ 47 , 52 ], post-weaning piglets [ 47 , 55 ], and pre-weaning and post-weaning calves [ 53 ]. In some reports, body weight tended to be higher in post-weaning piglets [ 50 ] and in calves [ 57 ].…”

Added flavors: potential contributors to body weight gain and obesity?

Background Added flavors are a marker for ultra-processing of food and a strong link exists between the intake of ultra-processed food and the development of obesity. The objective of the present article is to assess animal and human data elucidating the impact of added flavors on the regulation of food intake and body weight gain, as well as to define areas for future research. Main text Mechanistic studies suggest that added flavors induce overeating and body weight gain by two independent mechanisms: Added flavors promote hedonic eating and override homeostatic control of food intake, as well as disrupt flavor-nutrient learning and impair the ability to predict nutrients in food items. Supporting these potential mechanisms, added flavors increase feed intake and body weight as compared to non-flavored control diets in a broad range of animal studies. They are actively promoted by feed additive manufacturers as useful tools to improve palatability, feed intake, and performance parameters. In humans, added flavors are extensively tested concerning toxicity; however, no data exist concerning their impact on food intake and body weight. Conclusions Added flavors are potential contributors to the obesity epidemic and further studies focusing on their role in humans are urgently required. These studies include obesity interventions specifically targeting food items with added flavors and cohort studies on independent associations between added flavor intake and metabolic, as well as cardiovascular, morbidity, and mortality.
